IP Telephony with TAPI 3.0
White Paper
Abstract
TAPI 3.0 is an evolutionary API providing convergence of both traditional
PSTN telephony and IP telephony. IP telephony is an emerging set of
technologies that enables voice, data, and video collaboration over existing
LANs, WANs, and the Internet. TAPI 3.0 enables IP telephony on Microsoft®
Windows® operating systems by providing simple and generic methods for
making connections between two or more computers and accessing any
media streams involved in the connection.
TAPI 3.0 supports standards-based H.323 conferencing and IP multicast
conferencing. It uses the Windows*2000 operating system’s Active Directory
service to simplify deployment within an organization and includes quality-of-
service (QoS) support to improve conference quality and network
manageability.
